METHOD OF REDUCING RISK OF DELAMINATION OF A LAYER OF A SEMICONDUCTOR DEVICE

摘要

A method of minimizing de lamination of a layer (14, 16, or 18), the method includes providing a semiconductor substrate (12), forming a first layer (14) over the semiconductor substrate, wherein the first layer has a first corner (20) and the first corner has a first angle of approximately 90 degrees; forming a second layer (16) over the first layer, wherein the second layer has a second corner (20) and the second corner has a second angle of approximately 90 degrees, and modifying the first and second corners to form a first slanted edge (50, 60, or 70) of the first layer and a second slanted edge (50, 60, or 70) of the second layer, wherein the first slanted edge and the second slanted edge are continuous with each other and the first slanted edge forms a third angle with respect to the semiconductor substrate, wherein the third angle is less than 30 degrees.
